WINDMILLL.

SPECIFICATION forming part of Letters Patent No. 506,804, dated. October1'7, 1893.

Application filed January 31, 1893. Serial No. 460,212. (No model.)

To all whom it may concern:

Be it known that I, JOHN WALLACE, a citizen of the United States,residing at Union, in the county of McHenry and State of Illinois, haveinvented certain new and useful Improvements in Windmills; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

The present invention has for its object to provide a Wind-mill thatwill be simple in construction, possess the'required strength anddurability, and be effective and practical in its operation as a powerto run a pump, or for other purposes to which the mill may beapplied,which several objects I attain by the con structionsubstantially as shown in the drawings and hereinafter described andclaimed.

Figure 1 of the drawings represents a side elevation of my improvedwind-mill. Fig. 2 represents an elevation thereof partly in section;Fig. 3, a top plan view of the wind mill; Fig. 4, a horizontal sectiontaken on line 00 w of Fig. 1; Fig. 5, a detail perspective View of oneof the heads showing the bearing shoulders for the stems and braces ofthe sails, said View being taken on line y y of Fig. 1.

The wheel of the wind-mill is composed of a plurality of sails A, eachof which has suitably connected to it one end of a brace a, the lower oropposite end of the brace being attached to a head B which is providedwith hearing shoulders I) and seats 0 to form a more firm and rigidconnection between the head and braces. The stems d of the sails areconnected at their free ends to a head Owhich is similar in constructionto the head B, that is to say, it is provided with hearing shoulders andseats.

The several sails A are connected together by braces D, one end of eachbrace being attached to the outer side of the sail and the opposite endof the brace to the inner side of the sail next to it, thus forming aperfect brace throughout the several sails and rendering them moreserviceable. The manner of connecting the opposite ends of the braces tothe outer and inner sides of the sails respectively, secures increasedstrength and durability.

A suitable bracket E supports the operating parts of the wind-mill, andforms a hearing for the shaft F to'which the wheel is connected throughthe medium of the headsB C. The shaft F is screw threaded at its end tore ceive jam-nuts e for holding thereon the head and enabling it to beadjusted on the shaft as circumstances require. Upon the shaft F iskeyed a suitable bevel gear wheel G with which engages a pinion I-I uponthe upper end of a vertical rod I, said rod extending down through atube K and has upon its lower end a yoke f to form a bearing for thepump or other rod L. The rod L has upon its upper end a gear wheel orpinion g which meshes with the teeth of a gear wheel h upon the lowerend of the tube K. The gear wheel h and pinion g form a guide for therodL as it is being carried around by the rod I and as the rod looselypasses through the'collar f upon the end of the yoke f, said rod L whenmoving around the gear wheel will also rotate upon its axis through themedium of the gear wheel and pinion. A compound motion will there- 'forebe imparted to the rod L which may be utilized with any pitman device orsuitable arrangement of gearing. Should the rotation of the rod L uponits axis not be required, the pinion upon the end thereof may beremoved.

A sleeve M encircles the tube K and has connected to it, one end of achain 4;, said chain passing over and against a pulley upon the tube andthen upward through the sleeve and over a pulleyl and thence around apulley m, after which the end of the chain is attached to the end of anarm N to which the vane O is connected. The sleeve M has connected to itone end of a second chain at which chain extends up through the tower Pand over a pulley 0 and a pulley p and has its end connected to the stem7 of the vane. The pulleys Z 0 are suitably connected to the bracket Eand the pulleys m p are connected to arms 8 upon the ends of the rod B,said rod being suitably attached to the bracket.

The tube K has a longitudinal flange 25 to serve as a guide and preventthe sleeve M turning thereon, said sleeve having a flanged collar u toreceive a clutch T upon the upper end of a rod U, the clutch working ina guide '0 when moving up or down and is intended to be operated fromthe ground. A rod Vhas its end pivoted or hinged to the arm N and itsopposite end passes through a guide w upon the rod R, and a coiledspring W encircles the rod V between the guide and its point ofattachment with the arm, as shown in Fig. 3.

The rod Vsets the vane of the wind-mill at any desired angle, and thespring is designed to hold chains taut when the mill is not in Therearemanychangesand modificationsin the several details of constructionthat could be made without departing from the principle of my invention,and therefore I reserve the right to make any such changes-in theinvention as would be considered as coming within ordinary mechanicalskill.

Havingnow fully described my invention, what'I claim as new, and desireto secure by- Letters Patent,is-

1. In a wind-mill, the vertical tube K connecting with the pump or otherred through the medium of suitable gearing,a rod I extending through thetube and connected with the pump rod, and to the wind-wheel by suitablegearing, a longitudinal guide flange 15 upon the tube, in combinationwith the sleeve M having flanged collar u, the rod U and clutch T foroperating the sleeve, and suitable chains and pulleys to form aconnection between the sleeve and vane of the wind-mill, substantiallyas and for the purpose set forth. 2. In a wind-mill, the vertical tubeK, the sleeve M-connecting with the vane through the medium of suitablechains and pulleys,

:and the rods I U connected together, and the =1 former connected to thetube by suitable gearing, in combination with the pivoted or hingedrod 1) and thespring W, and the rod R'having arms 3 and :pulleysconnected thereto, substantially as and for theipurpose set forth.

In testimony that I claimthe above I have hereunto subscribed my name inthe presence of two witnesses.
